ABSTRACT

A dispenser of liquid products for sanitization, such as bactericides, germicides, disinfectants, alcohol gel, moisturizers, among others, featuring innovative construction characteristics which distribute the product onto the user&#39;s hands or onto surfaces of various objects, via spraying in micro droplets, enabling a uniform distribution, suitable to be installed in public environments such as restrooms, restaurants, malls, offices and commercial facilities.

TECHNICAL FIELD OF THE INVENTION

This invention patent refers to a dispenser of liquid products forsanitization such as bactericides, germicides, disinfectants, alcoholgel, moisturizers, among others, in which, notably, said dispenserfeatures innovative construction characteristics that enable uniformdistribution of the product on the user's hands or onto surfaces ofvarious small objects; for this purpose, the dispenser is designed witha vertical structure or a spraying chamber, which includes a reservoirwith minimum capacity of 2.5 liters and a pressure pump above 7 Bar,both provided in the lower section of said structure and associated to aspraying nozzle located on the upper section of said structure, in linewith an access inlet. Therefore, when the user places his/her handsthrough the access inlet, the liquid or gel product is sprayed in microdroplets, which adhere and cover the entirety of the desired surface,decreasing consumption of the dispensed product and increasingdistribution efficiency.

BACKGROUND OF THE INVENTION

As is widely known, the use of alcohol gel or other bactericideproducts, germicides and disinfectants have become increasinglyfrequent, necessary, and mandatory. Models for dispensers of liquid,gel, or foam products, such as soap, alcohol gel, moisturizers, amongothers, are usually used in public locations such as restrooms,restaurants, malls, offices, and various commercial facilities, in orderto facilitate product access, as well as its replenishment.

Currently, countless dispenser models for said liquid, gel or foamproducts are known, in which the manual model is basically comprised ofa bottle-type reservoir with a dosing valve mounted onto the nozzle,which, when pressed down, dispenses the liquid/gel/foam product onto thehands of the user.

The drawback of this manual dispenser model lies in the fact that theproduct is dispensed according to the force applied by the user onto thedosing valve associated to the course of the activation trigger, thusallowing higher or lower product amounts to be dispensed.

Another drawback lies in the fact that constant valve handling fordispensing liquid/gel/foam product in a public location is notrecommended due to the accumulation of impurities and dissemination ofbacteria, germs, and viruses, particularly, during a pandemic.

Another dispenser model, which is widely known in the market, isautomatic and also comprises a reservoir with a pumping mechanism forthe liquid/gel/foam product, reserved and assembled into a batcher, inturn, activated by a detection sensor or infrared device that dispensesthe liquid/gel/foam when the user's hands approach.

The drawback of the automatic model, similarly to the manual mode, liesin the fact that the product is dispensed as a jet and on a single spot,a feature that hinders uniform spreading, thus depending on rubbing ofthe user's hands.

In a search carried out on specialized databases, documents referring tospraying were found for dispensers for liquid or gel products, such asbactericides, germicides, disinfectants, alcohol gel, moisturizers,among others, such as document No. BR 20.2017.006301-7 which refers toan automatic dispenser for commercialization of cleaning products placedinside a self-servicing machine for commercialization and provision ofliquid cleaning products, which comprises a dispenser window; LCDdisplay; selection button; confirm button; dispenser nozzle; bottle;charge cell; credit card machine; money bill reader; coin reader; hose;motor pump; container; motor pump valve; electronic board; dosing valveor flow sensor and dispenser.

Document No. BR 20.2018.007939-0 refers to a dispenser to store liquidsoap or alcohol gel which may be attached directly to the container usedfor water transportation, on the truck's lower section or chassis; thisproduct provides greater convenience to truck drivers which need tosanitize their hands several times during their trips.

Document No. BR11.2018.076230-0 discloses a liquid dispenser forparticular discharging of pharmaceutical liquids, including a dischargehead and a cover, with a vent opening included on said cover'sstructure. Provision of an injected extraction segment is proposed,which, on a supply state, covers the vent opening and is tightly heldtogether with the cover structure. This extraction segment is joinedwith an originality segment, which, in the supply state of thedispenser, prevents removal of the cover structure, part of a separablesegment of the cover structure from the cover. In another configuration,the vent opening is provided with an air current filtering membrane,with the cover structure including two partial structures that jointlyassemble a housing chamber for the filtering membrane.

The aforementioned documents, although belonging to the same field ofapplication, are distinguished from this invention, as may be seen inthe following sections, thus ensuring that it fully addresses the legalpatentability requirements.
